Architectural plans were submitted to planning officials Thursday, as first reported by The Nashville Business Journal. The submission was in advance of the Downtown Code Design Review Committee hearing on Jan. 3.

The first 20-story tower will rise more than 300 feet above 10th Ave. N., at 1001 Church Street. The second tower will follow, completing the company's so-called Operations Center of Excellence.

The tech giant will begin hiring workers in 2019. They will have offices at WeWork until the new facilities are finished in 2021 or 2022.

The first building will include 11 levels of stacked parking, a bike storage room and an area for on-site daycare, according to the plans. On the fifth level, a "green roof" amenity deck will be available to employees.

A new roadway will also be built above 10th Ave. N. to increase access to buildings and shops.

A Grand Hyatt hotel is under construction now. Also planned for the development is Anschutz Entertainment Group's $44 million music venue, club, boutique hotel, movie theater and bowling facility set for a 2021 opening.
